Fix:
query = "select<seq2seq4repair_space>KEY(e),<seq2seq4repair_space>KEY(e).fName<seq2seq4repair_space>from<seq2seq4repair_space>Department<seq2seq4repair_space>d,<seq2seq4repair_space>" + "<seq2seq4repair_space>in<seq2seq4repair_space>(d.emps)<seq2seq4repair_space>e<seq2seq4repair_space>order<seq2seq4repair_space>by<seq2seq4repair_space>d.deptId" ;
